From 22cd7ebc075483d2977393429260df818072fa52 Mon Sep 17 00:00:00 2001
From: Vratko Polak <vrpolak@cisco.com>

Subject: Trending: New sensitive detection

This enables PAL to consider burst size and stdev
when detecting anomalies.

Currently added as a separate presentation_new directory,
so the previous detection is still available by default.

TODO: If the state with two detections persists for some time,
create a script for generating presentation_new/
(from presentation/) to simplify maintenance.
